Pick photos with one clear subject
A single person, pet, mascot, or object usually works better than a crowded scene. Stickers need a clean focal point so users instantly understand what they are sending.
Remove visual clutter
Transparent backgrounds, soft outlines, and simplified shapes help a photo-based sticker feel intentional instead of like a pasted screenshot.
Design the pack around use cases
Think about where the photo stickers will be sent: family chats, work messages, fan groups, social comments, or private jokes. The use case should guide the expressions.
